Pentax 50mm A lens
Just got one of these from someone on eBay. Is it correct that to move
the aperture ring beyond f11 requires depression of the button on the ring? On my 28mm ring the button is only required for the A position. Thanks, Daniele |

This is true for all of my lenses. -- Al Reid |

I was about about to point you to The Fine Manual, but looking at http://www.pentaximaging.com/files/p.../SMCLenses.pdf on the Pentax corporate web site tells me that that manual really isn't of much use. jue |

On my 28mm ring the button is only required for the A position. Thanks, Daniele You may have been sold a defective lens. The "A" position on the 50mm lens is just beyond f/22, and the button is pushed to allow the aperture ring to advance to that position, and then lock it in place. If your aperture ring does not advance beyond f/11, something is wrong. You may want to ask the seller why this was not disclosed . . . I'd send the lens back and buy another one without any defects. KEH.COM sells reliable used gear. |

It's pretty clear that the lock on the aperture ring mechanism is faulty, and gets stuck just before f11. It can be moved past this by holding down the lock button (though I can hear a metallic click as it goes past). The lock button should stay down until the ring is in the A position, but it rises after f8. What are the chances of having this repaired at a reasonable cost, or even of doing it myself?
